Eggs in Vinegar: What Happens?

Category Food trivia

You will see tiny bubbles on the eggshell.The eggs will have very small bubbles, barely noticeable, attached to the surface of the shell. If left long enough, a sticky substance may form on the eggshell, but it is unlikely that the shell will dissolve completely in 24 hours.

The principle is: the main component of the eggshell is calcium carbonate.Acetic acid is the main component of vinegar. Acetic acid can react with calcium carbonate to produce carbon dioxide. The ion equation is: carbonate ion reacts with hydrogen ions to form water and carbon dioxide.

This principle can be applied in real life for removing scale.
